Tubeless Valve Kits by Silca

An attention to detail is something the engineering at Silca has excelled at for almost 100 years. I’m really excited to Introduce the newest release of SILCA Tubeless Valve Stem Kits and Platinum Tape. These kits add strength, reliability, and aero-dynamics to your ride where the ‘rubber meets the road’.

Developed after years of struggling with heavy brass valve stems or fragile uber-lightweight aluminum stems, Silca Tubeless Valve Stems were engineered to present a perfectly optimized solution. Extracted from the finest cold drawn aluminum bar (rather than hollow extrusion), the Silca Tubeless Valve Stem design yields a refined stem weighing less than half of the brass valve stems, yet remain 50-200% stronger in comparison to common lightweight aluminum valve stems. The Speed Shield prevents carbon rims from being scratched or damaged by the valve nut and are optimized with spherical interface to the stem nut to eliminate bending forces which can lead to poor sealing or worse, valve stem failures.
